boot

Overview ¶

Command boot allows to handover a system running linuxboot/u-root to a legacy preinstalled operating system by replacing the traditional bootloader path

Synopsis:

boot [-v][-no-load][-no-exec]

Description:

If returns to u-root shell, the code didn't found a local bootable option

-v prints messages
-no-load prints the boot image paths it was going to load, but doesn't load + exec them
-no-exec loads the boot image, but doesn't exec it

Notes:

The code is looking for boot/grub/grub.cfg file as to identify the
boot option.
The first bootable device found in the block device tree is the one used
Windows is not supported (that is a work in progress)

Example:

boot -v - Start the script in verbose mode for debugging purpose
